Ah, you'd be using Cloudflare's email routing. If Cloudflare's MTA can deliver over IPv6, you should be ok, as only they would be delivering to the subdomain and everyone else would deliver to Cloudflare first. However, on the outbound, if the mx.myserver.com sends directly, you may run into issues there with servers that don't have a AAAA record on their MX - unless you proxy to a smarthost that can do IPv4.

I was thinking to use cloudflare email routing for incoming messages. for example, domain.com points MX to mx.cloudflare.net And, sub.domain.com points MX to mx.myserver.com mx.myserver.com has ipv6 only. When u...@domain.com gets messages from internet, they are accepted by cloudflare. Then clouflare forward them to u...@sub.domain.com. So user read messages in the mailbox of u...@sub.domain.com. Surely they can send messages by the sender u...@domain.com. Thanks for all the kind answers. regards. > The interesting things is how is you priority set? > Is the IPv6 MX the highest? _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
